Trimming Data Out of Inconsistent Character Lengths

Anonymous — Fri, 08 Jan 2016 16:49:13 GMT

Hello All,

Any ideas on how I can cut the numbers starting with '62*' out of these multi-character length strings? the field is "The Key" in the attached qvw. There is a lot of inconsistencies in these strings, and i was hoping there was another way other than trim() or len() to determine where to start cutting. The result should look like what's found in the field "The Answer" with just 6 digits. I used the Mid() Excel function to get "The Answer". Any help would be much appreciated.

Thanks a lot!

Something like this? (code to add to your load script)

Mid(SubField([The Key], '/', 3), 4) AS [The Answer],

Result:

Best,

Peter

Hi Peter,

This is super close. I just need the last character trimmed off of your result. I played with the parameters of your given functions and can't really get it to 6 digits in length (ie. 621103). However, i know i can do a resident load and use len(). If we can't get it done in one line, i'll still mark you correct. Thanks a ton and Happy New Year.

I guess you didn't try hard enough

Just add a third parameter 6 to the Mid() call. Like:

Mid(SubField([The Key], '/', 3), 4, 6) AS [The Answer],

You can use the same expression in an UI object as well. If you need this value as a key value, use the script version.

If you want me to upload a corrected copy of your document, just let me know.

Have a happy and healthy 2016!

Peter
